Thanks for the bug report. Why was this HAVE_PTHREAD_SIGMASK
patch needed? Your email doesn't say. MirBSD has
pthread_sigmask, according to
<https://www.mirbsd.org/htman/i386/man3/pthread_sigmask.htm>,
so pthread_sigmask should work.

Thanks. Does the following patch fix things for you? If you
don't have the autotools installed you can simulate it by
substituting "pthread_atfork" for every instance of "pthread_self"
in the file "configure".
